Permit/key application form

Tackle Requirements

No tackle is required for the main routes, although a 10 metre handline is recommended for the climb down at Keyhole Chamber, where P-bolts are installed. These are the only official fixed aids in the cave. The integrity of in-situ ropes is not not guaranteed and you use them at your own risk.

Flooding

Certain sections of the cave are prone to flooding. In moderate flood, the area around 3rd Boulder Choke sumps, and in heavier flood conditions 2nd Boulder Choke and the narrow section of Turkey Streamway above Northwest Junction become impassable.
Lower Main Stream becomes impassable and can sump upstream from Southern Stream Passage junction. Also, Maytime floods dramatically.
